. tion.

In centrifugal machines used in various branches of industry, thematerial to be treated is introduced into a drum mounted on a verticalspindle and provided with an insertion or centrifugal vessel havingperforated walls, from which the material to be treated passes into thespace between said vessel and the walls of the drum and is dischargedfrom the same. As in many of these apparatus the only problem to besolved is to separate the material introduced from liquid ingredients,it being immaterial what shape the materials remaining in the perforatedcentrifugal vessel assumes and at what part of said vessel the liquidconstituents pass out, therewas not any reason for using any but avertical arrangement of the spindle. It may, however, be desired to drythe material which remains in the perforated centrifugal vessel asquickly as possible, in which case it is preferable that the material bedistributed evenly over as great an area as possible, particularly onthe bottom of said vessel as well as on the sides, and also that aportion of the substance to be separated off shall be able to passthrough the bottom of the centrifugal vessel while the latter isrotated. In order to effect this it is necessary to depart from thehitherto generally customary arrangement of a vertical spindle andmoreover to compel the substances which are to be separated off not onlyto pass out through the sides of the centrifugal vessel but alsovthrough its bottom. In order to bring this about in a reliable manner,and also in case of need in order to dry quickly the residue containedin the said vessel, a suction device is combined with centrifugalmachines according to the present invention, which carries off through ahollow shaft the substances to be removed from the centrifugal vessel.

In the accompanying drawing a diagrammatic illustration of an apparatusaccording to this invention is given by way of example.

vOn a iiXed frame l are secured by means of bolts two standards 2. Inthe standards 2 is mounted the lower frame 4 provided with a segment 3,which frame can be set in any desired oblique position on said standardsand held firmly in such position by means of screws 5. The drivingpulley 7 is mounted on the driving shaft 6, but said shaftmay be drivendirectly by an electric motor or. by any other suitable means. In theframe 4 is mounted the hollow spindle 8 connected in any desired mannerto the' suction pipe 9. The hollow spindle 8 terminates in thecentrifugal drum 10 provided with a centrifugal vessel 1l of which boththe walls and bottom 12 are provided with perforations. The centrifugaldrum l0 is closed above by means of a cover 13 in any suitable manner,said cover being provided with a hopper 14 through which the material tobe treated is introduced. y

If it is desired that the material remaining behind in theperforatedcentrifugal vessel shall assume a certain shape, thus, that it shallbecome deposited not only against the sides of `said vessel but also onits bottom, then the machine is set obliquely and the driving mechanismand the suction device are started, so that said device removes throughthe hollow shaft the substances centrifugally ejected from said vesseland causes the residue deposited on `the walls and bottom of said vesselto dry quickly.

What I claim as my invention and desire to secure by Letters Patent 1. Acentrifugal machine comprisin in combination a frame, a revoluble ho lowshaft, adjustable means for supporting said shaft on said frame at an'igle inclined to the horizontal, means for r ring said shaft, and acentrifugal hollow dri/.l-ffmounted on and coaXially with said shaft andprovided with an inner centrifugal vessel having perforated sides andwalls, the interior space of said drum communicating with the interiorspace of said hollow shaft.

2. A centrifugal machine comprisin in combination a frame, a revolubleho low shaft, adjustable means for supporting said shaft on said frameat an angle inclined to the horizontal, means for rotating said-shaft, acentrifugal hollow drum mounted on and coaXially with said shaft andprovided with an inner centrifugal vessel having perforated sides andwalls, the interior space of said drum communicating with the interiorspace of said hollow shaft, a suction device having a suction pipe, andmeans connecting said suction pipe with said hollow shaft.

3. A centrifugal machine comprising in ICO IIO

combination a frame, a revoluble hollow shaft7 adjustable means forsupporting said shaft on said frame at an angle inclined to thehorizontal, said adjustable means oomprising an adjustable memberrevolubly supporting said shaft and adjustably mounted upon said frameand means adapted to Clamp lsaid adjustable member to the frame, meansadapted for rotating said shaft, and a centrifugal hollow drum mountedon and coaXially with said shaft and provided with an inner centrifugalvessel having perforated sides and walls, the interior space of saiddrum communicating with the interior space of said hollow shaft.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
